Stretched clusters for Azure VMware Solution (AVS) is now Generally Available, providing 99.99% uptime for mission critical applications that require the highest availability. With this release, customers can use Customer-Managed Keys to encrypt the stretched vSAN.

- Improved application availability
- Provide a zero-recovery point objective (RPO) capability for enterprise applications without needing to redesign them or deploy expensive disaster recovery solutions.
- A private cloud with stretched clusters is designed to provide 99.99% availability due to its resilience to AZ failures.
